Application filed March 15, 1321, Serial No. 452,411.

This invention relates to glass working machines of the type used in the manufacture of glassware by blowlng, such machines having intermittently movable tables for parison receiving and blowing molds. In practice the tables are usually driven by compressed air supplied to cylinders, the piston rods thereof being connected to oscillating arms associated wit-h the tables to movethe same so that the parison may be transferred from a station on one table to a blowing station on the other table. V

The invention forming the subject matter of this application appertains more particu larly to an air'supply system, or arrangement of pipes, air control valves, and means moving the tables and locking them, which system may also include another control valve and accessories to actuate a kickout for the parison receptacles.

An air supply system whi h accords with my, invention has a main supply pipe that communicates dir ctly with control valves for cylinders, the piston rods thereof oscil- .lating arms to intermittently move the tables, air under pressure beingsupplied to the control valves, then to the cylinders to effect movement of the two tables at predetermined intervals.

My invention also includes locks for the tables and actuating means for the locks comprising pistons that are operated by air pressure supplied through branches of the air system connected-to pipes which extend from the control valves to the cylinders whose piston rods actuate the table moving means. i

The invention further consists in providing the table for the parison receptacles with a kick out, the air supply therefor being connected with the control valves for the table moving and locking means.

My invention also includes in combination with an air line system for table moving and locking instrumentalities, means for synchronizing the movements of the tables, the locks thereof, and a kick out for parison receptacles, the elements being or ganized for automatic operation, as will be hereinafter set forth.

The invention further consists in the construction, arrangement and organization of parts, as will be hereinafter set forth and claimed. In the accompanying drawings,--

Figure 2 illustrates a horizontal longitudinal section of a cylinder or casing for a control valve;

Figure 3 illustrates a vertical longitudinal section of the cylinder or casing, thevalve thereof being shown in full lines; and

a Figure 4 illustrates a transverse section on the line 44 of Fig. 3, this view being projected from Fig. 2.

The invention forming the subject matter of this application is adapted for use in connection with glass working machines of that type manufactured under several Letters Patents of William Miller of Swiss-- I vale, Penn, for instance Patent Number 1,515,962, which are adapted tomake jars,

bottles and the like. Referring to the drawings, 1 is a table or support for the parison receptacles, 2 the table or support for the blow-molds, said tables being intermittently rotated by piston rods 3 and 4 which are connected to oscillatory arms 5 and 6 attachedto dependingshafts of the tables, as is common, to insure lntermittent rotation of the table. The piston rods are reciprocated at the proper intervals by air admitted into the cylinders 3 and 41 and the tables between the oscillations ofthe arms 5 and 6 are held or locked against rotation by vertically movable pins 7 and 8, which when elevated enter recesses formed in the under sides of the tables.

Air under compressionfor moving the tables and the locks is supplied through a main supply pipe 9 and its branches 10 and 11, such branches being connected to centrally positioned ports12 of the cylinders or casing of 13 and 14L for control valves of similar construction.- The cylinder 13 has ports 15 and 15? and the cylinder lt has ports 16 and 16, said ports being located to one side of the transverse centers of the cylinders, and said cylinders are also provided at their ends with openings or ports 17, 17' and 18, 18', said ports preferably extending through the heads of the cylinders.

The cylinders or casings for the control valves (see Fig. 3) have ways 19 which communicate by openings 20 and 21 with the valve chamber adjacent to the ends thereof and the way 1911s also provided with a cen-.

tral opening'22' located oppositethe port 12.

The casings or cylinders have threaded apertures for the reception of bolts 23 of a length to extend into theway-19 the bolts when adjusted to suit the normal pressure in the main air line 9 determining the amount of air that will pass through the openings 20 and 21 in a given time,

The control cylinders have therein cylin-. dri'ca'l sliding valves or spool valves 24 which have peripheral heads 25' and 25 positioned adjacent to the ends andacentral peri heral portion 25 of l'es s width than the leads, the length of the valve being less than the distance between the heads oi" the cylinder.

The casing or cylinders 13 and 14 which are supplied with air under compression directly from the constant pressure supply pipe 9are connected by pipes 26, 26 and 27, 27 with the cylinders and 4 and these pipes are. connected to pipes 28, 28 and 29, 29" with" the cylinders 30 and "31 which have therein piston heads the piston rods thereof eagagingieversv' and 8 which carbeyond'their fulcrums, pins 7 and 8 that engage with recesses or stops on the unc er surfaces of the tables. The table engaging pins and thellevers are carried by suitably supported frames which also maintain springs which tend to hold the pins raised and the pistons depressed. J

The cylinders13'and1 14'at their ends have ports which are alternately closed by the reciprocation of the control valves 24, and these ports 17, 17 and 13, and 18' communica te with pipes 32, 32 and'33, 33, the ends of saidpi-pes having valves with springs for holding the same against theirs'eats.

The valves 9', 10, 11 and 12 in practice will he moved from their seats by suitable means as rods or pins operated either by air pressure or mechanically by suitable timing mechanism under air control or by cams or the like that are actuated fr'omthe shafts of the table supports.

When it is desired to" associate the table actuating and locking means with a kick;

out for the parison receptacles and to have the same operate synchronously or in proper time relation with the movement of the table 1, or with a transfer mechanism, I provide a cylinder 34 h ving therein a control valve of similar construction to the valvesof cylinders 13' and 1-4. The end ports ofthe cylinder 34 are connected by pipes 35 and 35 with pipes 32 and 33 and the endsof said pipes are provided with valve cas in gs 1Q and'l l. The" port of the cylinder 34which correspondswith the ports 15 and 16- ot' the valve} casings 13' and -14 i's connecte'dby'a pipe 36 whichextends; to the upper portion of a cylinder 37 which contains a kick; out piston for the? sses; The pipe 36 has spyass on connection: 38' that extends to one; end of a timing cylinder 89',

the piston therein having-a rod for moving the valve9 ina casing 40- off itsseat. The port of cylinder 34 which corresponds with ports 15 and'lfi of cylinders 13 and 14 is supplied with a pipe 41 that extends to the lower-end ofthe kick out cylinder 37; a branch 42 of pipe 41 which has a manually op'eratedspeedcontrol cock or regulator 43 communicates with the timing cylinder 39. The cylinder 34 may be connected to the main-supply pipe 9 by a branch pipe 34, which corre'sp ndsWith thepipes 10 and-11 of'the casings 13 and 14. v

The kick out cylinder has -a valvedp'ort 44 whichis adaptedtobe covered by the piston head when in'lowered position.

The kick out rod of the piston-head whenyforced upward extendsthrough open ingsthrough the table 1, and 'engageswith a part of the receptacle to raisetheparison of molten and plastic glass;

Several valves are held upon their seats by springs so as" to be'normally closeda'nd the valves10", 11 and'12 in' practice will be moved from their seats mechanically by pins which are a'ctuatedfby cams on shafts which are actuated from the" shafts or r0- tary supports for the'tables;

By adjusting thebo'lts 23' the amount of air thaten'ters the cylinders 13', 14 and 34 through the ports 20 and 21 may beflregulated, and thus the reciprocation of the s 001 valves 24' can be synchronized ortime as to the admittance of air under pressure to move the table and the table locks at the proper moment by the full pressure supplied between the' heads or flanges and the center flange on the control valves.

The cylinder 34" is supplied with air under pressure by means ofa branch pipe'34 from pipe 9 which communicates with an inlet or openin 12'" of the cylinder 34-. This branch is similar to the branches 10 and 11 for thecylinder's 13'and' 14. I
